[0033] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0034] Because the conveying speed of the conveyor belt is too fast, when the conveyor belt stops and the robot arm needs to pick up the battery blocks, the tray loaded with battery blocks placed on the conveyor belt will be offset forward due to the original running inertia, resulting in the robot arm being unable to accurately pick up the battery blocks in the tray.

[0035] The present invention provides a first limiting portion on a supporting member carrying a battery block, and a second limiting portion on a transfer device. The first limiting portion cooperates with the second limiting portion to limit and fix the supporting member and the transfer device, and enables the supporting member to move synchronously with the transfer device without being affected by the inertia of movement and causing position deviation, thereby cooperating with a robot arm to accurately pick up and place the battery blocks.

[0036] in, Figure 1 is a schematic structural diagram of a battery transport mechanism disclosed in an embodiment, Figure 2 is a schematic diagram of the structure of the supporting member disclosed in the embodiment, Figure 3 This is a schematic diagram of assembling a ball screw on the second guide rail disclosed in the embodiment. Figure 4 It is a schematic diagram of the limiting and fixing of the supporting member and the transfer device disclosed in the embodiment.

[0037] like Figure 1-4 As shown, the embodiment of the present disclosure provides a battery transport mechanism, including: a first guide rail 100, a supporting member 200, a second guide rail 300 and a transport device 400, wherein the supporting member 200 is arranged on the first guide rail 100, and the supporting member 200 is provided with a first position limiting portion 210; the second guide rail 300 is arranged parallel to the first guide rail 100, and the horizontal height of the second guide rail 300 is lower than the horizontal height of the first guide rail 100; the transport device 400 is arranged on the second guide rail 300 and is located at the lower end of the first guide rail 100, and the transport device 400 reciprocates along the length direction of the second guide rail 300, and the transport device 400 is provided with a second position limiting portion 410;

[0038] The transfer device 400 can move at the lower end of the supporting member 200 , and when the second limiting portion 410 corresponds to and cooperates with the first limiting portion 210 , the transfer device 400 can drive the supporting member 200 to move synchronously.

[0039] Specifically, the supporting member 200 is used to support the battery block 700. The supporting member 200 is in movable contact with the first guide rail 100 and can move back and forth along the length direction of the first guide rail 100. The supporting member 200 can be in a rectangular, square, circular, etc. shape, and the contact method with the first guide rail 100 can be that a groove adapted to the first guide rail 100 is provided at the lower end of the supporting member 200, and the first guide rail 100 is embedded and installed in the groove at the lower end of the supporting member 200. The supporting member 200 uses the clearance of the groove and the first guide rail 100 to stably slide back and forth on the first guide rail 100. The groove and the first guide rail 100 also have a guiding function, so that the supporting member 200 can avoid angle deviation during the movement, resulting in the position deviation of the battery block 700 assembled at the upper end, which causes the robot to be unable to accurately pick up, affecting work efficiency and delaying the work rhythm.

[0040] Both ends of the first guide rail 100 extend to different processing sections respectively. For example, one end of the first guide rail 100 extends to the battery block 700 dispensing processing section, and the other end extends to the battery block 700 cleaning processing section. The supporting member 200 mounted on the first guide rail 100 supports the battery block 700 and runs between different processing sections to perform corresponding processing until it is packaged and shipped.

[0041] Since the horizontal height of the second guide rail 300 is lower than that of the first guide rail 100, the horizontal height of the transfer device 400 arranged on the second guide rail 300 is lower than that of the supporting member 200, and the transfer device 400 can reciprocate along the length direction of the second guide rail 300 at the lower end of the supporting member 200, and when the battery block 700 to be processed is assembled on the upper end of the supporting member 200, the transfer device 400 moves along the second guide rail 300 to the lower end of the supporting member 200, and the second limiting portion 410 and the first limiting portion 210 are used to cooperate with each other to realize the fixed connection between the transfer device 400 and the supporting member 200, and the supporting member 200 is driven to move by the transfer device 400, and runs between different processing sections.

[0042] The transfer device 400 may be a mobile trolley mounted on the second guide rail 300, and driven by its own motor to move along the second guide rail 300. A ball screw may also be provided on the second guide rail 300, the ball screw being provided along the length direction of the second guide rail 300, and driven by the motor to rotate the ball screw so that the nut on the ball screw performs linear motion along the length direction of the ball screw, and the nut is fixedly mounted with the transfer device 400, thereby realizing the reciprocating linear motion of the transfer device 400 driven by the motor of the ball screw on the second guide rail 300.

[0043] The battery transfer mechanism disclosed in the present application is provided by arranging a supporting member 200 on a first guide rail 100, assembling a battery block 700 to be transferred on the upper end of the supporting member 200, and arranging a second guide rail 300 in parallel with the first guide rail 100, and arranging a movable transfer device 400 on the second guide rail 300. A first limiting portion 210 is arranged on the supporting member 200, and a second limiting portion 410 is arranged on the transfer device 400. Due to the need to cooperate with the robot, the movement mode of the transfer device 400 needs to be frequently started and stopped. In this process, the first limiting portion 210 cooperates with the second limiting portion 410 to limit and fix the supporting member 200 and the transfer device 400, and the supporting member 200 moves synchronously with the transfer device 400, and will not be affected by the inertia of the movement and cause the position to deviate, so as to cooperate with the robot to accurately pick up and place the battery block 700.

[0044] In some embodiments, there are multiple first limiting portions 210 and multiple second limiting portions 410, and the first limiting portions 210 on the supporting member 200 and the second limiting portions 410 on the transfer device 400 are correspondingly arranged.

[0045] Specifically, the plurality of first position limiting parts 210 are arranged at intervals at any position of the supporting member 200, and can be dispersedly arranged along the circumference of the supporting member 200, or can be arranged at intervals and in the center. In this case, the second position limiting part 410 on the transfer device 400 should be arranged in a corresponding direction to the first position limiting part 210. The corresponding arrangement can be understood as that the interval distance and arrangement position of the plurality of second position limiting parts 410 on the transfer device 400 are the same as the arrangement of the plurality of first position limiting parts 210 on the supporting member 200. In this way, when the transfer device 400 moves to the lower end of the supporting member 200, the second position limiting parts 410 and the first position limiting parts 210 can correspond one to one.

[0046] In some embodiments, the first limiting portion 210 is a through hole 211 disposed on the supporting member 200 , and the second limiting portion 410 is a lifting plug-in 411 vertically disposed on the transfer device 400 .

[0047] Specifically, the through hole 211 penetrates the supporting member 200, and the lifting plug-in 411 can be inserted into the through hole 211 by lifting itself, so as to achieve the limit between the transfer device 400 and the supporting member 200, wherein the lifting plug-in 411 can be understood as a piston rod on a piston cylinder provided on the transfer device 400, and the piston cylinder can be a hydraulic cylinder or a gas cylinder, and the piston rod on the hydraulic cylinder or the gas cylinder can perform linear extension and contraction motion relative to the cylinder body, and the piston rod is used to extend into the through hole 211 of the supporting member 200. Among them, the diameter of the piston rod is slightly smaller than the aperture of the through hole 211, so as to achieve clearance fit.

[0048] The piston cylinder may be fixed at the lower end of the transfer device 400 by bolts, and the piston rod passes through the transfer device 400 and extends vertically.

[0049] In order to cooperate with the robot, the movement of the transfer device 400 needs to be started and stopped frequently. In this process, the first limit part 210 and the second limit part 410 are coordinated. In this embodiment, a lifting plug-in 411 is used to extend into the through hole 211, so that the supporting member 200 and the transfer device 400 are limited and fixed, and the supporting member 200 moves synchronously with the transfer device 400 without being affected by the inertia of movement and causing position deviation.

[0050] In some embodiments, the lifting plug-in 411 is further provided with a support portion 412 , and the support portion 412 is located between two ends of the lifting plug-in 411 and is circumferentially arranged around the lifting plug-in 411 .

[0051] Specifically, based on the lifting plug-in 411 mentioned in the previous embodiment as a piston rod, a support portion 412 is provided in the middle section of the piston rod, the support portion 412 is arranged around the piston rod, the support portion 412 is provided with a support end, the support end is a horizontal end face and is perpendicular to the axis of the piston rod, and the support portion 412 can be a support block or a support plate fixedly arranged on the piston rod, and the arrangement method can be welding. The support portion 412 can also be a support block or a support plate movably arranged on the piston rod, by arranging an internal or external thread structure on the piston rod, and arranging a corresponding external or internal thread structure on the support portion 412, and by rotating the support portion 412 and using the thread structure to achieve adjustment of the relative position on the piston rod.

[0052] Among them, the support part 412 is used to support the supporting member 200. When a part of the piston rod extends into the through hole 211 of the supporting member 200, the supporting end of the support part 412 contacts the lower end surface of the supporting member 200. As the piston rod continues to extend, the support part 412 lifts the supporting member 200 and separates it from the first guide rail 100. At this time, the through hole 211 can be set at the surrounding positions of the end of the supporting member 200 so that the support part 412 can lift the supporting member 200 smoothly and separate it from the first guide rail 100.

[0053] The transfer device 400 lifts up the supporting member 200 and transfers the supporting member 200 to the guide rail of another processing section, and then the piston rod of the lifting plug 411 contracts and detaches from the through hole 211 of the supporting member 200. The transfer device 400 is separated from the supporting member 200, and the transfer member returns to the initial position along the second guide rail 300 to transfer the next supporting member 200. At this time, the supporting member 200 is transported by other transfer devices 400 on the guide rails of other processing sections.

[0054] In some embodiments, the first limiting portion 210 is disposed at the lower end of the supporting member 200, and the second limiting portion 410 is disposed at the upper end of the transfer device 400; the first limiting portion 210 is an electromagnet, and the second limiting portion 410 is a metal part, or the first limiting portion 210 is a metal part, and the second limiting portion 410 is an electromagnet.

[0055] Specifically, the limiting cooperation between the first limiting part 210 and the second limiting part 410 can also be achieved by means of electromagnet and metal magnetic attraction. A plurality of first limiting parts 210 are arranged at the lower end of the supporting member 200, and a second limiting part 410 is arranged at the upper end of the transfer device 400. When the transfer device 400 moves to the lower end of the supporting member 200, the first limiting part 210 and the second limiting part 410 are in contact with each other. At this time, the first limiting part 210 can be set as an electromagnet, and the second limiting part 410 can be set as a metal part; or, the first limiting part 210 can be set as a metal part, and the second limiting part 410 can be set as an electromagnet. Among them, the material of the metal part can be iron, nickel or cobalt. The electromagnet is energized to absorb the metal part to achieve the limiting fixation of the first limiting part 210 and the second limiting part 410.

[0056] In order to cooperate with the robot, the transfer device 400 needs to start and stop frequently. In this process, the first limit part 210 and the second limit part 410 cooperate with each other. In this embodiment, the electromagnet is energized and the metal part is magnetically attracted to fix the supporting member 200 and the transfer device 400, and the supporting member 200 moves synchronously with the transfer device 400 without being affected by the inertia of movement and causing position deviation.

Two slide grooves are arranged at intervals at the lower end of the supporting member 200. The setting direction of the slide groove is the same as the extension direction of the first guide rail 100. The slide groove can be understood as a groove. The supporting member 200 is mounted on the first rail and the two parallel first rails are respectively embedded in the slide grooves, so that the supporting member 200 can be stably arranged on the first rail 100. When the transfer device 400 drives the supporting member 200 to move, the first rail 100 plays a role of moving guide.

[0059] In some embodiments, the supporting member 200 further includes an assembly frame 500 , and the assembly frame 500 is disposed on an end surface of the supporting member 200 facing away from the first guide rail 100 .
